How the signal engine works

Crypto candles come from Binance, with Coinbase and CryptoCompare as fallbacks. Stock candles come from Yahoo Finance's free chart endpoint — the only reliable no-key stock source, but unofficial, and it only produces new candles during market hours. Before anything is scored, each series passes a sanity check for mismatched lengths, negative prices, impossible candles, stale data, and single-candle outliers.

The model always takes a side. If the 9-period EMA is above the 21-period EMA it reads LONG; otherwise it reads SHORT. A real trader always has a lean, so direction is never "no opinion" — the confidence score, not the direction, is what tells you how much weight to give it.

Four independent checks either agree with the direction or they don't: RSI sits in a healthy band for that direction, the MACD histogram has the matching sign, the EMA gap held for three consecutive candles (a chop filter), and the same lean was present one candle earlier (confirmation). Each agreement adds one point out of four.

Both are derived from ATR-14, the average true range: the stop is one ATR away from price, and the target is 1.5 ATR away. That gives a consistent risk-to-reward frame instead of a round-number guess. Hold time is estimated by dividing the target distance by the recent average per-candle move.

Confidence is out of 100: raw signal strength contributes up to 30 points, the quality checks up to 25, higher-timeframe agreement up to 25, and the recent backtested hit rate for that exact setup up to 20. Anything at or above 70 is labelled high, 40-69 moderate, below 40 low.

Stock entries give direction only — bullish maps to calls, bearish to puts — plus a suggested expiry window derived from the estimated hold time. They never suggest strikes, premiums, or greeks, because that requires paid options-chain data this project does not have access to.

Everything published here is scoped to what a standard retail brokerage account can do, and Robinhood is the account this project is modeled on: commission-free stock, ETF, options and crypto trades, fractional shares, and both asset classes in one app.

The model reads price data only: it has no view on news, earnings, regulation, or liquidity shocks. Free data sources can rate-limit or change without notice. Backtested hit rates are computed over a small recent window and are not a performance record. It is wrong regularly, and everything published here stays public whether it was right or not.

How does an AI trading signal work?

It reads recent price candles and calculates the same technical indicators traders use by hand — trend (EMA 9 vs EMA 21), momentum (RSI 14), and MACD histogram — then turns the result into a single direction, a stop loss, and a target. There is no prediction of news or sentiment; it is arithmetic on price, applied identically every run.

What is a confidence score in trading?

Here, confidence is a 0-100 number blending four things: raw signal strength (30 points), how many independent quality checks agreed (25 points), whether the higher timeframe trend agrees (25 points), and how this exact setup performed in recent backtested history (20 points). A high score means the checks lined up — not that the trade will win.

Is this a good time to buy bitcoin?

This site cannot answer that for you. It shows what a mechanical model currently reads in BTC price data, including its stop loss and target, and it is wrong a meaningful share of the time. Treat it as one input, do your own research, and speak to a licensed professional before investing.

Is this free AI crypto analysis, with no signup?

Yes. Every signal on the board is public, there is no account, no email capture, and no paywall. The project is funded by optional donations.

How often does the board update?

Every 6 hours. The signal engine runs on a server schedule, writes its output to this site's database, and the Live Board shows a countdown to the next run and the timestamp of the most recent run.

Which brokerage are these signals built around?

Robinhood. The board only publishes things a standard retail account can act on: spot crypto, US stocks and ETFs, and simple call-or-put direction on options. Signing up through our referral link gives you a randomly chosen free stock after you link a bank account, and gives us one too — it costs you nothing and does not change what the model publishes. Robinhood does not endorse this site.
